THis is a cool idea. I absolutely loved the nonfiction book called “The Odds” by Chad Millman that is about Las Vegas sports betting and follows the NCAA basketball season. It is fascinating how the odds are determined and how people are professional sports bettors. I guess the NCAA really does produce the most betting of any non-superbowl event. All the newspapers, and sports cable companies have their own little tournaments to enter, of course just for fun! Good Luck with this! I think it is interesting that you are doing games to no skill like lottery, coin flips, along with games that people think they can beat like sports betting and poker. I wonder which will win more for you?
